stream_set_write_buffer — Sets write file buffering on the given stream

说明

intstream_set_write_buffer
( resource$stream
, int$buffer
)

Sets the buffering for write operations on the given stream
to buffer bytes.

参数

stream

buffer

The number of bytes to buffer. If buffer
is 0 then write operations are unbuffered. This ensures that all writes
with fwrite() are completed before other processes are
allowed to write to that output stream.

返回值

Returns 0 on success, or another value if the request cannot be honored.
